board. After being processed by the control board, the IP packets are transmitted
upstream to the upper level device through the optical or electrical port.
l In the downstream direction, the forwarding logical decapsulates the IP packets from the
Ethernet, performs CAR on the IP packets, reorganizes the IP packets into ATM/PTM
packets, and transmits the ATM/PTM packets to the interface module. The interface
module converts the ATM packets into analog signals and transmits the signals to
subscriber lines.
